TO ALL WHOM IT MAY CONCERN:

Be it known. that I, P. SrDEVLAN, of Jersey City, in the county of Hudson, and State of New jersey, have invented .a certain new and useful Improvement in Journalqund Axle-Boxes, of which the following is a full, clear, andexact description, reference being had to the accompanying drawing, which forms part of this specifi cation, and in which- Figure 1 represents a longitudinal, and v Figure 2 a transverse section of an axle-box, having my improvement applied to it.

. Similar-letters of reference indicate corresponding parts.

My invention consists in the combination with or application to axle or journal-boxes of wood in the form of strips inserted within the same in an intermediate or intervening manner relatively to the entire bearing, composed, say, of metal, or of material essentially different in character from said strips, which may either be saturated with petroleum or other lubricating oil or matter previous to insertion, or.ser've by their absorbent character to convey lubricating matter from a suitable supply to-the axle or shaft during its rotation to and throughout the bearing, and preferably extending to theends of the same.

These wooden strips may be variously arranged, and of anysuitable number, width, or thickness. In the accompanying drawing they are shown as arranged longitudinally with the axle, and extending the full length of the box. Thus A is a metallic axle-box, and B are the wooden strips, inserted.say in dove-tail or othershaped grooves, a, extending it may be the length of the box, and of an interior curvature corresponding'or thereabouts to the rotundity'of the axle. By thus, or otherwise in asubstantially similar manner, combining wood in strips with the harder material of the box, to constitute the bearing, a more perfect lubrication may be. kept up, while a solid basis is established for the shaft or axle, and every facility aflorded for renewing from time to time the wooden strips, as such is rendered necessary by wear or otherwise.

What I claim as my invention, and desire to secure by Letters Patent, i s- The combination, with a metallic or other hard journal or axle-box, of strips offwoodinserted. in dove-tail grooves therein, substantially as shown and described. I p i -P. S. DEVLAN.
